MARTHA VON TRAUTMANN, OF NEW YORK, N. Y.

ATOMIZER.

Specification of Letters Patent.

Patented Sept. 20, 1910.

Application filed June 24, 1910. Serial No. 568,636.

To all whom it may concern:

Be it known that I, MARTHA VON TRAUT- MANN, a citizen of the United States, residing at New York city, county and State of New York, have invented new and useful Improvements in Atomizers, of which the following is a specification.

This invention relates to an atomizer of novel construction which effects a very minute reduction and wide distribution of the liquid to be sprayed.

In the accompanying drawing: Figure 1 is a side elevation of an atomizer embodying my invention, Fig. 2 is a longitudinal section through the nozzle, Fig. 3 a section on line 3-3, Fig. 2 and Fig. 4 a bottom view of the cup.

The nozzle of the atomizer consists essentially of a disk 10, which forms the bottom of a cup 11, and extends laterally beyond said cup to form an upper circumferential groove or channel 12. This channel communicates with the interior of the cup by means of a series of liquid ducts 13 passing through the wall of the cup, directly above disk 10.

The lower face of disk 10, has a beveled edge 14:, and within this edge are formed a series of upwardly directed steam or gas ports 15. From disk 10, there depends a hollow stem 16 having upper perforations 17. Upon stem 16 is mounted a collar 18 which is adapted to be held against the lower face of disk 10, by means of a screw coupling 19, engaging the lower threaded end of stem 16, a washer 20 being preferably interposed between collar and coupling. The top of collar 18 is dished to form an annular chamber 21 between disk 10 and collar 18, said chamber being entered into by perforations 17, and also by ports 15.

The apparatus with which the nozzle is used, is shown to be of the following con struction: A frame 22 supports a water boiler 23, heated by lamp 2 1. A steam pipe 25 connects boiler 23 with a superheater 26 heated by lamp 27. Superheater 26 is in turn by pipe 28, and coupling 19 connected to stem 16. Upon frame 22 is further supported by arms 29, a tank 30 adapted to contain a suitable medicinal or odoriferous liquid. Tank 30, communicates by a valvecontrolled pipe 31, with cup 11, said cup having a flanged upper inlet aperture 32, for the reception of said pipe.

In use the superheated steam, or other suitable gas under pressure flowing from pipe 28 into hollow stem 16, passes through openings 17 into annular chamber 21, and is thence ejected through ports 15 in the form of a series of upwardly directed jets. The liquid to be atomized flows from tank 30 and pipe 31 into cup 11, and thence through ducts 13 into the annular groove 12. Here the liquid meets the steam or gas jets emitted through ports 15, and is by said jets thoroughly atomized, in the form of a fine spray or cloud. Owing tp the effective reduction and general diffusion obtained by the apparatus, it is specially adapted for disinfecting and similar medical purposes, though it may of course be used equally well for the toilet.

I claim:

1. An atomizer comprising an apertured cup, a disk forming the bottom thereof, a hollow stem depending from the disk, a collar mounted upon said stem, and having a dished top to form an annular chamber between collar and disk, ports connecting the interior of the stem with said chamber, and ports leading out of said chamber.

2. An atomizer comprising a cup, a disk forming the bottom thereof and extending beyond the wall of the cup to form an upper groove, liquid ducts passing through said cup into said groove, and gas ports cooperating with the liquid ducts.

3. An atomizer comprising an apertured cup, a laterally extending beveled disk forming the bottom thereof, ports formed in the beveled disk, a hollow apertured stem depending from the disk, and a dished collar mounted on the stem.

1. An atomizer comprising an apertured cup, a liquid tank communicating therewith, a laterally extending disk forming the bottom of the cup, a hollow stem depending from the disk, a dished collar mounted on the stem, and forming an annular chamber intermediate collar and disk, ducts connecting the interior of the stem with said chamber, ports leading out of said chamber, and a steam or gas pipe connected to the stem.
